Sound needs a medium in which to travel
. Sound waves cannot form unless there are molecules to bump into each other to pass the wave form along. Sounds will therefore not travel in space where only a vacuum exists.
Do mechanical waves require a medium?
Waves that
do require a medium
are called mechanical waves.
Why does sound only travel through a medium?
Sound waves can be described by the wavelength and frequency of the waves. Sound travels more quickly through solids than through liquids and gases because
the molecules of a solid are closer together and, therefore, can transmit the vibrations (energy) faster
.
How do sound waves travel in the air medium explain?
As sound passes through air (or any fluid medium), the particles of air do not vibrate in a transverse manner. Explanation:
Sound energy comes in the form of waves as a result of vibration, and it travels by creating waves in the particles of its medium
.
What type of wave does not need a medium to travel?
Explain that two categories of waves are mechanical and electromagnetic. Mechanical waves use a medium for their energy to travel.
Electromagnetic waves
travel without a medium.
Which of the following waves require a medium to travel?
EXPLANATION: The
sound wave
requires some medium to propagate because it is an example of the mechanical wave. So option 1 is correct. Microwaves, radio waves, and gamma rays are electromagnetic waves.
What is a medium in sound waves?
Sound is a type of energy made by vibrations. These vibrations create sound waves which move through mediums such as
air, water and wood
. When an object vibrates, it causes movement in the particles of the medium.
Where sound waves Cannot travel?
Sound can not travel in
a vacuum
. A vacuum is an environment where liquids, gases, or solids of some sort are absent. If there are no objects then the sound waves do not have particles to vibrate, which means the sound waves can not travel.
Does sound travels only in air?
Sound waves can travel through any substance, including gases (such as air)
, liquids (such as water), and solids (such as the seafloor).
Do sound waves travel in air?
Sound can travel in air at approximately 332 metres per second
. This is fast but not nearly as fast as light which travels at 300 000 kilometres per second. This difference in speeds enables us to appreciate that sound does take time to travel.
Which of these waves require a material medium?
Mechanical waves
, unlike electromagnetic waves, require the presence of a material medium in order to transport their energy from one location to another. Sound waves are examples of mechanical waves while light waves are examples of electromagnetic waves.
Which of these does not required a medium?
Radiation are electromagnetic waves that travel without any medium
, Rest conduction and convection takes place in specific medium. Was this answer helpful?
What happens to sound if there is no medium for it to travel through?
As the vibrations of the particles reach your ear, your ear drum receives the vibrations which the brain then interprets as sound. In the vacuum of space, there are no (or very, very few) particles to vibrate, so
sound cannot travel through this medium.
Which medium will sound travels the fastest?
The speed of sound depends on the medium in which it is transported. Sound travels fastest through
solids
, slower through liquids and slowest through gases.
What are the two things required for a sound wave to travel?
Sound waves need to travel through a medium such as solids, liquids and gases. The sound waves move through each of these mediums by
vibrating the molecules in the matter
. The molecules in solids are packed very tightly. Liquids are not packed as tightly.
When sound waves superimpose they can interfere?
When two waves of similar frequency arrive at the same point and superimpose, they
alternately constructively and destructively interfere
. This alternating is known as a beat because it produces an unpleasant pulsing sound.
